Abstract
An invention is disclosed that optimizes resource management within a Packet Data Serving Node PDSN. This is accomplished through the modification of a Authentication, Authorisation and Accounting (AAA) server. Specifically, when a node (e.g., mobile node) is authenticated by a AAA server in response to a request by a target PDSN to which the node has roamed, the AAA server may send a disconnect request message to a source PDSN indicating that the node has moved from the source PDSN. In this manner, the source PDSN is notified that it should terminate its session with the node and release resources associated with the session (e.g., Point-to-Point Protocol session). The source PDSN may then send a message to the AAA server indicating whether the session was successfully terminated and whether the resources associated with that session were released).
